The wick is made of a high grade of cotton or linen. The material is woven (or braided) so that it will burn in one direction and will curl so that its end remains in the candle flame's oxidizing zone for even and intense burning. Often, wire-core wicks are used.
Differentiate among the non-urinary waste management systems. The excretory system is a passive biological system that removes excess and unnecessary materials from the body, so as to help maintain homeostasis and prevent damage. The main organs involved in waste management are the skin, lungs, liver, and kidneys.

Different waste products are excreted in different ways. Plants break down waste products at a much slower pace than animals. They convert a lot of their waste into useful substances through photosynthesis. Gaseous wastes are excreted during respiration through the plant's stomata and root cell walls. At night, when photosynthesis cannot occur, excess water is released through the tips of the leaves. Other waste products are released as leaves and flowers fall off of a plant. In addition to oxygen, water and carbon dioxide, other plant waste products include resins, saps, latex and tannins.
